DIY polypropylene plumbing: schemes

If you are faced with the task of improving living space, then surely you have already thought about how to build water from polypropylene with your own hands. Metal pipes are now a thing of the past because of their lower performance. But with the use of polypropylene, the system can be assembled even by a novice master. If you make work on the technology, the water supply will serve more than 50 years, and the cost of the arrangement will be minimal.

Preparatory stage

If you decide to lay a plumbing pipe of polypropylene with your own hands, then it will be important to choose components for the system taking into account operating conditions. The decisive factor is the working pressure and temperature of the transported fluid. Polypropylene products are made in several versions, each of which is intended to work in certain conditions.

Material selection

When visiting a building materials store, you will need to pay attention to the labeling. Thus, if you see the designation PN10 on the product, this will indicate that the pipes are intended to supply extremely cold water. If you need a product for transporting both hot and cold liquid, you should choose the one on whose surface there is a PN 16 marking. For arranging heating systems, products with the designation PN 20 are used.

If you need to equip your own water pipe made of polypropylene, it is important to consider that a liquid that has a temperature of more than 60 degrees contributes to the expansion and sagging of pipes, so the PN 20 and PN 25 grades have reinforcement in the form of aluminum foil or fiberglass, which is usually not required at installation of a water supply system. For this, the first two mentioned pipe modifications should be preferred.

Features of system design

If you are thinking about how to make plumbing out of polypropylene with your own hands, then initially make a detailed scheme. To begin such a project should be with the definition of options.The connection of the main line to the individual technical devices can be carried out in an open or closed way. The second option is more complex and implies the need for professional skills as well as accurate calculations. It is understood that all pipes that will be located in the wall will be devoid of joints.

Specialist recommendations

Interface areas should be available for audit and maintenance work. Plumbing in the apartment with their own hands from polypropylene is much easier to lay the method of open wiring. It provides for the installation of products in vertical planes at the corners of the room, whereas in the horizontal it occurs on the level of the floor. This technology is chosen when there is a need to make the layout less visible. Among other things, during a possible leakage, it will always be possible to notice shortcomings and eliminate them in time.

Types of wiring for water supply

Plumbing in the house with your own hands from polypropylene can be mounted on the basis of sequential wiring. It is also called the tee system and provides for the sequential lead of the pipeline from the main line to the points of water consumption.Two pipes, one of which is designed for hot, while the other for cold water, should extend from the riser with an introductory locking device. From them with the use of tees are organized tap to all points of consumption. The main advantage of this technology is cost-effectiveness, because the minimum amount of materials will be used, in addition, the master will be able to complete the work without any problems.

Among the shortcomings can be identified dependence of plumbing devices from each other. This indicates that if you need to disconnect one device, you will have to shut down the system. This negative factor can be neutralized by installing shut-off valves on separate branches. Among other things, if several water consumption points are activated simultaneously, pressure drops can occur. The tee acts as a fairly voluminous node, so it is not always possible to find a place for it in the bathroom. If you decide to equip the plumbing of polypropylene with your own hands at the cottage, then you should choose the sequential layout, as this option is the most economical and requires the least amount of material.

Collector wiring system

Such a system is also called parallel and provides for a collector, which has a single input and several outputs. The number of the latter should be equal to the number of consumption points. Each separate tap should be connected to an individual outlet. Before you make a plumbing of polypropylene with your own hands, you need to consider all the advantages of the described wiring system. Among them it is possible to highlight the absence of the need to break the system when a separate plumbing fixture breaks down. Water will be distributed to all points evenly, which indicates that at the time of pressure drops, all devices will receive an equivalent volume of liquid. All system control devices are concentrated in one place, namely in the collector cabinet. This indicates the possibility of installing on the outputs of metering devices to ensure a certain pressure in a particular device.

If you will be equipped with a water pipe made of polypropylene with your own hands at the cottage, you will need to prepare the schemes in advance. After all, you have to decide which type of layout will be selected.As disadvantages of the collector system, a significant number of divorces can be distinguished, which leads to a higher cost of the whole structure. Home masters note the complexity of installation work.

Rules for the installation of polypropylene products

Initially, it will be necessary to cut the pipe elements of the desired length. To work should use a special tool. To go from one diameter to another, you need to use special couplings, while for corners and turns you will need corners. In order to go around the pipe, you need to use a contour. Among other things, crosses, plugs and tees will be used. All these models are available in different diameters, so you need to carefully study the water supply scheme before purchasing.

In order to strengthen the pipe on the wall, you should apply clips. They need to be fixed in increments of 2 meters, which is true for straight line segments. Among other things, they are located in the field of corner mates. If the pipes need to be laid one on top of another, then double clips should be used. When working with risers, it is recommended to use steel clamps that have rubber pads as fasteners. The element will bend around the pipe, forming a kind of ring.It must be tightened using a nut or bolt. Professionals are advised to mount the rotation of the inner corner of the hot pipe in 3-meter increments from the wall surface.

Conclusion

If you decide to arrange a plumbing of polypropylene with your own hands, you will need diagrams for high-quality and competent work. However, it is important to keep the technology. Thus, the elements of polypropylene products must be interconnected by welding. Before that, initially you need to clean, and after degrease the cut pipe. The nozzle for the soldering iron must also be degreased. These rules must be taken into account.
